Woman mistakes builder’s foam for hair mousse, has really bad hair day BY Tobias Salinger NEW YORK DAILY NEWS Wednesday, September 30, 2015, 6:07 AM A Share this URL Richard Goerg>Ag/ Richard Goerg via iStock A file photo shows a can of building foam. A woman apparently mistook her can of the home sealant for her hair mousse. Here’s a true fashion emergency. A woman sprayed builder’s foam in her hair when she thought she was just using her mousse. The synthetic sealant apparently added some major poof to her hair. Pictures trending Tuesday with hashtags like “#badhairday” and “#DIY” show her waiting in an Eastern European emergency room after the mixup, Yahoo! UK reported. The woman is wearing a frown to go with a massive dried clump of the foam sitting atop her head. I love this from @imgur - what happens when you use builders expanding foam instead of hair mousse.. #badhairday pic.twitter.com/azalvtBcHt — Phil Williams (@PhilWilliams) September 29, 2015 The spray-on substance fills cracks around the house by taking their shape and expanding.
